Tesco is facing Britain's largest ever equal pay claim and a possible compensation bill of up to 4 billion pounds (C$7 billion), according to a law firm which has begun legal proceedings. It comes as a campaign for equal pay grows in the U.K.

In the past two decades, most corporations have implemented CSR governance and management systems and reported progress on their CSR objectives. The number of CSR reports has increased, as have the scope and quality of the information published. There were fewer than 50 CSR reports following Global Reporting Initiative (GRI) guidelines in 2000 but, by 2011, there were 3,000.

Additionally, CSR awards and social indexes that identify best-in-class companies — such as the Dow Jones Sustainability Index (DJSI) — have flourished.
